Photoshop Elements - FILE FORMATS

HappyFace_Lean.jpg
IF you haven't already done so - you should make a new "PHOTOSHOP" folder on your H: Drive to store your graphics work. Move your "Happy Face" graphic from yesterday's lesson to it, and open it up in PHOTOSHOP ELEMENTS

The Happy Face uses a FILE FORMAT called PSD (Photo Shop Document) that is ideal for storing graphic work in progress, but the filesizes can be MASSIVE.

PSD characteristics:
Advantage
Disadvantage
  • Every Layers and Layer Styles is saved and can still be edited
  • Every PIXEL of your graphic is preserved digitally exactly as it was created
  • Text Layers can be re-edited
  • The Filesize can be VERY large
  • The PSD can't be opened or used by very many other programs

Now try using FILE- SAVE AS (but don't actually save yet)
There are literally DOZENS of diffrerent graphic types available - here are the ones you'll use most often:

Photoshop_Files01.pngPSD is always shown at the top
- It is an "artists" format, but is not compatible with webpages or word processors

GIF is an old standard for webpage compatibility
- Ideal for Illustrations - it allows up to 256 colours in your graphic
- It can make your files very small if you know what you're doing

JPG is perhaps the most popular format on the web these days
- Ideal for digital photos - it allows millions of colours
- Compression is adjustable - trading off filesize for quality

PNG is a "Portable Network Graphic"
- Ideal for Illustrations - comparable but BETTER than GIFS

FORMAT EXERCISE
1. SAVE to different FORMATS
Use FILE - SAVE - AS and try saving your Happy face in EACH of the formats GIF, JPG and PNG to your BTT folder on your H: Drive
  • Just keep clicking OK to use whatever "settings" are currently displayed in photoshop

2. CHECK THE RESULTS
  1. CHECK THE FILESIZES
    1. Go to your H: Drive in windows where you saved your Happy Face copies
    2. Use RIGHT-MOUSECLICK to examine the properties of each of those file formats.
    3. Write down the filesize in BYTES for each of the four formats you've used so far
  2. CHECK THE QUALITY
    1. Open each of the GIF, JPG and PNG versions in Photosshop Elements
    2. Use the magnifying glass tool to zoom in to 300% and scroll to look at the area between the mouth and the bottom right side
    3. See if you can spot the "flaws" introduced by different file formats (you have to look closely). Which of GIF, JPG and PNG yields the BEST quality?
